حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا حُسَيْنُ بْنُ عِيسَى، أَخُو سُلَيْمٍ الْقَارِي عَنِ الْحَكَمِ بْنِ أَبَانَ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ لِيُؤَذِّنْ لَكُمْ خِيَارُكُمْ وَلْيَؤُمَّكُمْ قُرَّاؤُكُمْ "
It was narrated that Ibn 'Abbas said:
"The Messenger of Allah said: 'Let the best of you give the call to prayer (Adhan), and let those who are most versed in the Qur'an lead you in prayer.'"
